Monster waves the size of a six-story building broke at the famed surf spot, Mavericks along the San Mateo County coast of Northern California.
The waves on Thursday drew professional big wave surfers from around the world, but conditions were too chaotic for Titans of Mavericks to hold the annual surfing competition.
The surf contest known colloquially as Mavericks could still be held this season, depending on conditions.
